Title: Process for producing 1-naphtyl-acetic acid
Inventor: BALOGH LAJOS
IPC: C07C51/06
Filed: 1988-05-04
Abstract: Naphthyl-acetic-acid is prepd. from naphthalin via two intermediate, namely 1-chloro-methyl-naphthalene and 1-naphthyl-acetonitrile. The sequence of reaction steps occurs in a heterogeneous system without separating intermediates from the reaction mix. Chloro-methyl-naphthalene is prepd. first in closed system at 70-85 deg.C with an excess pressure of gaseous hydrochloric acid. It is then converted to 1-naphthyl-aceto-nitrile in an azeotropic solvent mixt. of iso-propanol and water, containing 5-20wt.% of water and in the presence of potassium-iodide. - The prod. is finally hydrolysed to 1-naphthyl-acetic acid in the presence of satd. aq. sodium-hydroxide at 100-140 deg.C. The prod. - is purified by fractional precipitation in a function of pH.

Title: Process for removing heavy metals from waste waters and process for producing precipitating agent for them
Inventor: FUELOEP JULIUS
IPC: C02F1/52
Filed: 1989-05-24
Abstract: The invention relates to a process for separating heavy metals from waste water and to precipitant for carrying out this process and to process for manufacturing the precipitant. It known to use the alkaline hydroxide precipitation and the sulphide precipitation to separate heavy metals from waste water. However, these known processes are associated with serious disadvantages which, in the final analysis, have prevented their use in practice. The invention proposes, in a process according to the generic part, to combine the intrinsic advantages of sulphide precipitation in an acid medium, namely the extremely low residual solubilities of the heavy metals, with the considerable reduction in the risks of possible overdosage, i.e. safety from formation of hydrogen sulphide. The precipitant used is designed in such a way that the sulphide and other precipitates in the treated waste water automatically flocculate out at a pH of about 7.5, the sludge becoming separated from the clear water without addition of flocculating agents. The agent for separating heavy metals advantageously consists of alkaline earth metal polysulphides or mixtures of alkaline earth metal polysulphides with other alkaline earth metal sulphur compounds.
